Navigating the complexity of forecasting in multi-team environments is a challenge many in the Agile community face. This session demystifies how to forecast work (how long) involving multiple dependent teams with practical, real-world examples and techniques. Forecasting work inside a single team has become more accessible with good tools and techniques. However, understanding how work is built and flows between many dependent teams is still a dark art in many organizations. How long it takes one team to make part of a feature doesn't answer how long it takes to deliver a feature from beginning to end, which is a critical question when planning product features and releases. Organizations want to deliver work predictably. Choosing between many great ideas often depends on when they could be delivered live to customers. Forecasting how long something might take becomes an essential aspect of growing organizations. This session will give Agile product owners, and team leads practical ways to quickly forecast how long it will take to deliver a great idea across multiple teams. Join us on a journey into the complexities of forecasting at scale, and leave with actionable strategies you can implement in your organization.
